Description

On Android, when using a CollectionView nested within another CollectionView, I am unable to scroll within the inner CollectionView. When attempting to scroll within the inner CollectionView, the outer CollectionView is scrolled instead. I am able to select items within the inner CollectionView - it is only the scroll functionality that does not work.

This works as expected on iOS or Windows.

Steps to Reproduce

See sample application for layout.

1. Create a new Maui project.
2. Add a CollectionView to a ContentPage
3. In the DataTemplate of above CV , add another CV
4. Add enough data to both that they fill the container enough to be scrollable
5. Attempt to scroll in the inner CollectionView

Expected Result:

• The items in the inner CV should scroll
• The outer CV should only scroll when using whitespace outside of inner CV

Actual Result:

• The outer CV scrolls
